VTANUF'ACTURE OF LOADED HEELBLANKS.

SPECIFICATION forming part of Letters Patent No. 386,656, dated July 24, 1888,

Application tiled January 19, H88. Serial No. 101,232.

To all whom it may concern:

Beit known that I, Fanniaonn F. RAYMOND, 2d, of Newton, in the county of Middlesex and State of Massachusetts, a citizen of the United States,have invented a newand useful Improvement in the Method of Making Loaded Heel- Blanks, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

Heretofore loaded heel-blanks for flush nailing have been provided with a gang or group of nails placed closely together, and each of which is an attaching-nail; and I have ascertained that the use of so many nails for the purpose of attachment of the heel-blank to the hoot or shoe is objectionable, in that they do not serve to hold the heel-blank to the soles of the boot or shoe any more strongly, if as well, as though fewer attaching nails were employed; also, that the use ot' so many attaching-nails adds considerably to the cost of manufacture of the boot or shoe. It is still, however, desirable that the lower portieri of the heel-blank should have a larger metal wearing-surface than would be provided with a sufficient number of attaching-nails only, and to overcome the objection above named,and to provide a loaded heel-blank that shall have a proper metal wearing-surface, I make a loaded heel-blank as hereinafter specified.

Any form of heel-blank may be used. I prefer, however,to employ a compressed or molded heel-blank-that is, a heel that has been submitted to compression in dies, whereby a concave heel-seat is formed, its side edges consolidated, and a flat tread provided. The heelbla1ik,either while under compression or otherwise, has formed in ita number of holes, which, preferably, vary in length, the deeper holes being arranged for the reception of the longer attaching-nails and the shallower holes for the slugs or nails which do not serve as attachingnails. I prefer to form these holes of variable length in the heel-blank simultaneously by a gang or group of awls varying in length, and into the holes thus formed I then insert the attaching-nails and slugs, the attaching-nails of course being inserted in the longer holes and the slugs in the shallower holes, and I also prefer that the breast-nails,or the first nails in (No model.)

order from the breast, be attaching-nails, and the nails Afollowing in their order about the heel-blank may be alternated with slugs, as desired.

For ordinary uses I prefer to employ first an attaching-nail, then two slugs, then the next attaching-nail, and so on, and the attachingnails are driven into the heel-blank, but not entirely through the same, their' head ends projecting from the tread-surface of the heelblank. The slugs, however, I prefer to drive into the heel-blank so that their heads shall be flush with the surface of the tread, and I prefer to drive or insert the attaching-nails and slugs at the same ti nie-that is, as a gang or group-so that the attaching-nails shall be inserted with their heads left projecting,while the slugs shall be driven home and need no further driving with the subsequent attaching of the loaded heel-blank to the soles of the boot or shoe.

Of course it is not necessary that the slugs be driven completely home, but they should be driven far enough into the heel-blank to hold, and, as they are very much shorter than the attaching-nails-probably, as a rule not longer than the portion of the attaching-nails which are left projecting from the loaded blank-it is obvious that they must either be driven home or to a position which shall bring their heads considerably closer the tread of the heel-blank than the heads of the attachingnails.

In the drawings, Figure 1 represents a section of a loaded heel-blank made by my method upon the line or a: of Fig. 2. Fig. 2 is a plan view of such a loaded heel-blank. Fig. 3 is a section upon the line .fr x of Fig. 2. Fig. Lisa view on the same line, showing the slugs partially driven.

Having thus ['ully described my invention, I claim and desire to secure by Letters Patent of the United Statesl. Theimproved method of makingdetached loaded heel-blanks for attachment by llush nailing to the soles o a boot or shoe, consisting in pricking holes therein at a uniform distance from the edge ofthe top lift of the heel-blank and inserting in some of said holes nails of one length to serve as attaching-nails and the heads of which are left projecting from the tread-sur- ICO face of the heel-blank, and the points of which do not extend through the heel-blank, and -in other of said holes shorter nails or slugs adapted for surface wearing and not for attaching, and interposed between the attaching-nails, as and for the purposes specified.

2. The method of making detached loaded heel-blanks for attachment by flush nailing to 4the soles of a boot or a shoe, consisting in forming holes in the heelblanl varying in depth and inserting in said holes nails varying in length, the longer of which are used as attachng-nals, are set in the longer holes, and have their heads projecting from the tread-surface of the heel-blank and their points embedded in I5 the substance of the heel, and the shorter of which are set in the shallower holes and are interposed between the attaching-nails and are driven to bring their heads ush with the tread-surface of the heel-blank before it is atzo tached, as and for the purposes described.
